- This invention relates as indicated, to apparatus for handlingcylindrical articles such as barrels and the like, and 1s deslgne'dprimarily'to be employed as a means for the art of coating and treatingbarrels, any

mechanism that is employed in connection with the treating apparatus forthe purpose of feeding thereto, the cylindrical articles to be treatedmust be capable of feeding such articles singly, inasmuch as thetreating operation is carried on in connection with only one of sucharticles at a time, and further, such apparatus after the feedingoperation has been completed, must be capable of being positioned so asnot'to'interfere with the workmen who are employed in the process ofpainting or treating the articles. 7

Another requirement of the above described form of material handlingapparatus, is that when the feeding operation has been completed, suchapparatus will of itself return to the inoperative position so'as tomove out of the way of the operators, and further that while in suchinoperative position, the feeding of additional articles will berestrained until the operator elects to so feed a new article.

It is among the objects of my invention to provide an apparatus forhandling cylindrical articles which shall have all of'the above nameddesirable characteristics. Other objects of my invention will appear asthe description proceeds. To the accomplishment of the foregoing andrelated" ends, said invention, then, consists of; the means hereinafterfully described and particularly pointbarrel painting or coating machinewhich ineludes opposltely tapered conical rollers 2,

adapted toreceive the barrel and support the same on-its chime ringsduringthe painting.

'or' t eating operation, A pair of laterally spaced discharge skids 3,may be positioned in association with the paint machine'to carry awayfrom such machine, the barrels orlike articles which have been freshlypainted. In alignment withthe paint machine maybe an inclined conveyordown. which the barrels, or like cylindricalarticles are permitted toroll freely so that a new barrel is always in position to be fed to suchmachine by the apparatus J comprising my invention, which willnow bedescribed.

Theapparatus for feeding the barrels from the conveyor 4, or like meansto the, treating machine, or like means, consists of'a rotatable shaft5, which may be terminally provided with trunnionsfi here shownrotatively mounted in bearings carried by pedestals 7. The shaft 5- hassecured thereto, the axially spaced pivoted laterally spaced arms 8 and9, a

which serve as a means for conveying the barrels or like articles fromthe inclinefcon- Veyor 4, to the above described machine, or likemeans.- The arms 8 are provided with oppositely sloping terminalportions'lO'and 1 1' which are perfectly arcuate in formalthough sucharcuate form isnotnecessary to theopera-tionofthe apparatus. The spacebetween the oppositely sloping portions-1O 1 and 11 may be filled with acounterweight 12,

which will beof sufficient mass sothat the tainedthereby in thesubstantially vertical position illustrated by broken lines in Fig. 2.

' arms of the apparatus will be normally main- The arms 8 and 9, as wellas the terminal portions 10 and 11 thereof, are formed'from a pluralityof'plates such as 13,, which are in overlapping relation along theirends so :as

to provide oppositely-sloping upper surfaces for theIarmsS and 9,andtheir terminals l'o and 11, so'thatthebarrel, or likecylindricalarticle, will be supported only. on its chime rings or on the peripherythereof adjacent its ends so thatno-part off'the mechanism portionofthearticler p The operation of the above described apparatus is asfollows:

The arms 8 and 9, due tothe effect of the counterweight 12, or theweight of the termi-- nal portions 10 and 11 on the opposite side of thevertical plan passing through the ful crum point for the apparatus willnormally be in the broken line position illustrated in Fig. 2, so thatany barrels or cylindrical articles such as 15, positioned on theinclined conveyor 4, will be prevented from rolling off from the end ofsuch conveyor.- Upon counter-clockwise rotation of the arms as viewed inFig. 2, the oppositely sloping'arcuate portion 10 and 11 of the armswill cause a'single cylindrical article such as 16, to be fed to themachine in the manner which is apparent from an examination of Fig. 2.The arcuate portion 10 will engage the next succeeding barrel orcylindrical article and positely laterally sloping article-engaging armsadjacent said conveyor provided with longitudinally extending oppositelylaterally sloping portions for engaging such articles only on theirchime rings andfor singly feeding such articles from said conveyor ontosaid arms upon pivotal movement of said arms. v

prevent the same from rolling down the con- 7 i veyor during the feedingoperation of the article 16, and permit thearms upon release by theoperators, to again resume a substantially vertical position preparatorytos the next feeding cycle."

It is believed that a further description of the principles described inmy invention is unnecessary for those familiar with'the art, suiiice ittosay that numerous minor changes in the above described constructionmay be made without departing from the principles of my invention, and"Without losing any of the desirable advantages obtained thereby.

. Other modes of applying the principle of my invention may be employedinstead of the one explained, change'being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed. Y r Itherefore particularly point out and d1stinctly claim as my invention:

1. In apparatus of the class described, the

combination of a pair oflaterally spaced arms articles upon an inclinedconveyorand'singly feed the samelon to said arms upon pivotal movementthereof.

.2. In apparatus'for singly feeding cylindrical articles from aninclined supporting means on to other receiving means, a pair ofpivotally mounted arms providedwith .op-
